VENTILATING WINDOW-SASH- Specification of Letters Patent.

Patented Feb. 5, 1907.

Application filed October 31, 1.906. ASerial No. 341.401.

To a/ZZ whom it may concern:

Be it known that I, SAMUEL FELDMAN, a citizen of the United States, andresiding at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Ventilating Window-Sashes, of which the followin is a speciiication, such as will enablethose s illed in the art to which it appertains to make and use thesame.

This invention relates to means for ventilating a room or compartment,and the object thereof is to provide an improved Window-ventilator i'oraccomplishing this result independent of the window-frame andindepenlclient of any construction connected therewit The inventionconsists of a window-sash 'adapted to be mounted in a window-frame inthe usual manner and provided at one end,

either the top or the bottom thereof, with to pass freely through saidscreen when suchcondition is desired.

The invention is fully disclosed in the following speciiication, ofwhichthe accompanying drawings form a part, in which the separate parts of myimprovement are designated by suitable reference characters in each ofthe views, and in Which- Figure 1 is an inside view of the top of awindow-frame and showing the upper and lower sashes mounted therein andshowin my improved ventilatin device connecte with the top portion of te upper sash; Fig. 2, a transverse section on the line 2 2 of Fig. 1;and Fig. 3, a vertical section on the line 3 3 of Fig. 1.

In the drawings forming part of this specication, I have shown anordinary Windowframe comprising vertical side members a and a transversetop member a2, the bottom portion of the side members and bottomtransverse member being broken away together with the bottom part of thebottom` sash. Placed in the frame are the usual top and bottom sashes band c, and said sashes are provided with the usual transparent ortranslucent panels b2 and c2, preferably composed of glass, and in\thepractice of my invention, as shown in the drawings, I cut outtransversely the top art of the transparent or translucent panel If inthe top sash b to form atransverse opening d in the sash b, and withinthe opening thus formed I set or place a screen e. The screen e in theform of construction shown comprises a wire frame e2 and a body portionof wire mesh or other suitable material, and this screen rests directlyon the transparent or translucent panel b2 and is held in the sash b inthe same manner as said panel or in any preferred way. I also hinge tothe top portion of the sash b, as shown at f, a supplemental sashframeg, in which is placed a transparent or translucent panel g2, similar tothe panel b2, and thisv sash in the position shown in Figs. 1 and 2restsdirectly on the screen e, and the bottom part thereof covers theconnection between said screen and the panel b2, or, when desired, thesupplemental sash g may be raised to any desired extent and may be heldin the raised position by any preferred means, such as an ordinarytransom-lifter.

When the supplemental sash g is down, as shown in Figs. 1 and 2, theventilator is entirely closed, and the window-sash is as tight as if noscreen was laced therein; but when it is desired to use t eventilator-screen e the sash g is raised.

The sashes b (and c ma be provided with the usual lock h, by W 'ch theymay be locked together in the usual manner, and said sashes may bevertically movable and counterbalanced in 'the window-frame, or they maybe provided with any desired means for holding them in any position ofadjustment, and while I have shown my improved ventilator'applied onlyto the top portion ofthe upper sash it will be apparent that the samemay be aplplied to the top portion of either side or to t e bottomortion of either side.

Having fully descri ed my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A window ventilator, comprising a transverse screen set into the sashin an opening formed by removing a part of the transparent ortranslucent panel, and a supplemental sash hinged to the Window-sash andprovided with a transparent or translucent panel and adapted to coverthe screen when IOO in one position and to be swung aWay from the sameso as to permit air to pass therethrough.

2. ln a Window-ventilator, a sash having a 5 transparent or translucent'panel the top portion ot' Which is removed to form a transverse openingor space7 a ventilator-screen set into said space in the same plane asthe transparent or translucent panel, and a supplemental sash hinged tothe top portion of the main sash and adapted to cover said screen in oneposition and to be raised so as to permit air topass therethrough.

3. In a Window ventilator, a Window- [5 frame, a Window-sash mountedtherein, a

ventilator set into the Window-sash and occupying a space Jformed byremoving a part of the transparent or translucent panel therein7 and asupplemental sash hinged to the Window-sash and adapted in one positionto cover the ventilator and to be raised so as to permit air to passtherethrough.

4. -A Window-sash provided With a transparent panel Which only partiallyfills the same, the balance of said panel being filled by a screen, saidsash being also provided with a hinged 'and closed sash member adaptedto cover said screen.

In testimony that I claim the foregoing as my invention I have signed myname, in

resence of the subscribing Witnesses, this 30th day of October, 1906.V
